SHEET-METAL CAN.

Application led October 29, 1919.

To all whom it may concern.'

Be it known that l, yISAAC E. SiixroN, a citizen of the United States,residing at Boston, in the county of Suffolk and State oflilassachusetts, have invented new and useful Improvements inSheet-Metal Cans, of which the following is a specification.

This invention relates to a can used for containing liquids, andprovided with a pouring nozzle or mouth which is tightly closed when thefilled can is marketed, and is adaptedv to be repeatedly opened andclosed, the mouth being originally closed to afford a maximum protectionto the contents, and adapted to be opened and'closed, although not sotightly as before.

The invention is embodied in the improvements which l will now proceedto describe and claim.

Of the accompanying.,drawings forming a part of this specification,-

Figure 1 is a side view of a portion of a can provided with a mouthembodying the invention.

Figure 2 is a section on line 2--2 of Figure 1.

Figure 3 is a sectional view, showing the mouth and its neck and flangewithout the ca f Tn Figurel T show a portion of a sheetmetal can bodyhaving a sheet-metal mouth 13, here shown as a pouring nozzle. The mouth13 is a cylindrical tube, and is extended to form an annular neck 14projecting outwardly from the outer' end of the mouth, and forming anupwardly facing annular seat which limits the movement, to its operativeposition, of the cap hereinafter described, the said seat being in aplane at right angles with the axis of the mouth 13. 15 represents acylindrical tubular Harige extending inward from the outer -portion ofthe neck, and provided with an outwardly projecting lip 22 at its lowerend. The outer surface of the Harige 15 forms a cylindrical externalfriction face, which is coaxial with the mouth 13, and is flush with theouter margin of the neck 14, so that said neck does not obstruct themovement of the flange of the above-mentioned cap to its operativeposition.

rlllie body 13, neck 14, and lip 22 are integral with each other andconstitute a onepiece member, provided ,by suitably forming a sheetmetal blank. The cap hereinbefore referred to'includes a head 19, whichSpecification of Letters Patent.

is in a plane parallel with the seat formed by the neck 14 when the capis in place, and a cylindrical ange 2O integral with and eX- tendinginwardly from the head, and provided at its inner edge with an outwardlyprojecting annular lip 21. The inner surface of the cap flange 20 formsacylindrical internal friction face, adapted to cooperate with theexternal friction faceof the flange 15 in forming a tight frictionaljoint or union between the two flanges.

When the can has been filled, sealing means may be deposited on the seatformed by the neck 14, said means being, for example, a. cover 25,formed as shown by Figure 2. The cap is then forced to place until thecap head 19 abuts against the sealing means, and the cap Harige 20cooperates with the flange 15 in forming a firm frictional joint. Thearrangement is such that when said joint is formed, and the movement ofthe cap to its operative position is arrested by the neck 14, the lips21 and 22 are slightly spaced apart, to permit the removal of the cap bya prying tool inserted between said lips, the lip 22 constituting afulcrum for said tool. j

The lips 21 and 22 are preferably rolled to a substantially tubularform, so that they are adapted to support the pressure of a prying toolwithout being indented thereby.

ltt will be seen that the outwardly projecting neck 14 stilfens themouth 13, and leaves said mouth entirely unobstructed when the cap isremoved, so that it does not obstruct the flow of liquid from the can.Said neck supports the flange 15 without obstructing the externalfriction face of the latter, so that the internal friction face of thecap fiange is movable into and out of engagementwith the saidexternalfriction face.

T claim:

1. A sheet metal can comprising, in combination, a one-piece sheet metalmember including a tubular mouth, an annular neck bent outward from theouter end of the mouth, and a tubular flange extending inward from theneck, and provided at its inner end with an outwardly projecting annularlip, the external surface of the fiange constituting an external annularfriction face coaxial with and surrounding the mouth; and a capincluding a head and an annular flange projecting inwardly from the headand providedat its inner edge with an outwardly projecting annular lip,the inammala of the cap by a prying tool inserted between the lip-e.

2. A sheet metal can substantially as specified by claim l, 'the saidlips being' rolled to a substantially tubular form, and therebyadaptedto support the pressure of a pryin tool Without being indented thereby.
